Answer:

A = πr² = B

A = π(8)² = B

A = (3.14)(64) = B

A = 200.96 m = B

A = πrl + B

A = π(8)(25) + 201

A = 628 + 201

The sum of three prime numbers (other than two) is always odd.
grandymaker [24]

Step-by-step explanation:

The statement in the above question is True.

Sum of three prime numbers (other than  two)  is always odd.

Going by Christian Goldbach number theory ,

  • Goldbach stated that every odd whole number greater than 5 can be written as sum of three prime numbers .  

 Lets take an example,

  • 3 + 3 + 5 = 11
  • 3 + 5 + 5 = 13
  • 5 + 5 + 7 = 17

Later on in 2013  the Mathematician <u>Harald Helfgott</u> proved this theory true for all odd numbers greater than five.

The Z-score is based on the concept of the normal distribution, the fact that we can expect 95% of the values in the distributio
Dennis_Churaev [7]

Answer:

C.) In perfect health.

Step-by-step explanation:

Given an average weight of 15kg and a standard deviation of 3kg for children of 4 years. Since the weight is based on a normal Z - distribution of 95% which is mean ± 2(standard deviations)

Mean weight interval is :

15 - 2(3) ; 15 + 2(3)

(9 ; 21) ; this weight interval could be interpreted to mean the normal or perfect weight value.

Therefore, given that the child weighs 12kg

Since, 12 kg falls within in the interval, we can conclude that the child is in perfect health.
